Serial No. 736,510.

To all whom, it may concern:

1 Be it known that we, James F. 'IHOMAB and JOHN HA'NEY, citizens of'the United sition.

of the soil.

States, and residents of Odessa, in the county of Bigstone and State ofMinnesota, have made certain new and useful ImprovementsinGrading-Scrapers, of which the following is a specification.

Our presentinvention relates to grading scrapers, our object being toprovide a wheeled frame and a shovel scraper adjustably mounted in theframe in such manner that it may be caused to scrape and remove thesurface of the soil beneath the frame when the latter is moved, and maybe further adjusted to a position wherein its contents may be eitherdumped as a whole or gradually leveled out after transportation to adesired point.

With these objects in view our invention resides in the particularconstruction and arrangement and operation to be now described withrespect to the accompanying drawings, forming a part of thisspecification and in which Figure 1 is a plan view of our improvedinvention. Fig. 2 is a side elevation, the parts being in their normalinoperative po- Fig.' 3 is a sectional side elevation illustrating theshovel scraper adjusted into operative position for scraping the surfaceFig. 4 is a similar view illustrating the two dumped positions, theposition in which the contents of the shovel scraper are leveled outbeing shown in full lines, and that posit-ion in which the contents aresimultaneously dumped, being shown in dotted lines, and Fig. 5 is adetail section taken substantially on the line 55 of Fi 2. I

Reflarring now to these figures, A designates the frame of our improvedmachine, which is generally rectangular and comprises side bars aconnected at their rear ends by means of a platform (2 adapted tosupport the operator, and further connected at their forward ends bytransversebeams a which support the fifth wheel of the forward truck B,carrying a pole b and wheels 6. The intermediate portion of the frame,between the forward transverse supports a.

' and the rear platforma is open and in this space is disposed a shovelscraper C, this scraper being formed with a forward operating lip asidesc, and a rear wall 0 and being provided upon the said rear wall with aside extensions 0 which are adapted to rest upon the upper surface ofthe frame sides a at the forward edge of the platform a substantially asshown in Fig. 1.

At each side of the shovel scraper (l are arranged crossing braces orlevers D and E, the forward end of the brace or lever D being pivotallyconnected at d to the scraper adjacent its forward end and extendingrearwardly and having a longitudinal slot (1' through which extends atransverse shaft F which extends transversely between and through theframe sides a below the forward end of the platform a, the ends of thisshaft being secured by exterior nuts The forward end of the brace orlever E is pivotally secured at e to the respective frame side a and itsrear end is pivotally connected at e to the scraper side adjacent itsrear wall Thus it may be seen that the shovel C will be supported insuch a manner as to permit of its swinging adjustment as clearlyillustrated by comparison of Figs. 2, 3 and 4. In order to effect thisadjustment the U-shaped lever frame G is provided with a central handle9 extending over the platform a and having each of its forwardextremities g rigidly connected, by a nut it, upon a stud h which worksthrough a longitudinal slot a in the frame side a and constitutes anangular extension of a lever arm H, the opposlte end of which ispivotally connected at the point d at which the forward end of the braceor lever D is also connected as before described. Thus in the normallowered position of the lever frame G, the forward portion of the shovelscraper C is raised to the osition shown in Fig. 2. When it is desirehowever,nto lower the lip 0 into engagement with the surface of thesoil, the lever'frame G is raised to the position shown in Fig. 3,forcing the forward end of the shovel scraper downwardly.

In order to prevent raislng the rear end of the shovel scraper, a pairof upright hook members I are connected by a lever 2' having a handle 2"said members being pivotally mounted at their lower ends upon the shaftF before mentioned and being movable by means of the lever z' and itshandle so as to engage over the rear side extensions a of the shovelscraper as clearly illustrated in the first three figures. Thus in theposition shown in Fig. 3 wherein the scraper is engaged with the surfaceof thesoil so that upon forward movement of the wheeled frame A, thematerial is scraped up into the shovel O, the hook members I preventaccidental displacement of the parts. As soon as the shovel has filledwith material the lever frame is again lowered raising the shovelscraper to position shown in Fig. 2 and the material may be thentransported to any desired point where it is to be dumped. In dumpingthe handle z" is first moved rearwardly whereby to disengage the hookmembers I from the shovel extension c and the lever frame G is thenraised so as to lower the forward end of the scraper. If it is desiredto level out the material from the shovel, the shovel handle 7 c isgrasped and the shovel raised to the position'shown in full lines inFig. 4:, during the continued travel of. the wheeled frame. It will thusbe seen that as the material discharges fromthe lower end of the shovelit will be leveled out upon the surface of the ground by the lowershovel edge. If on the other hand it is desired to simultaneously dumpthe material the shovel handles 0 are grasped and the shovel moved tothe position shown in dotted lines in Fig. 4' and in this position itwill be noted that the material will be simultaneously discharged incase the leveling out is not desired.

We claim; V

1. In a scraper and grader, the combination of a wheeled frame, a shovelscraper disposed in the frame and having side extensions at its rear endresting on the frame sides, a latch mechanism movable to -engage anddisengage said shovel extensions, means for raising and lowering theforward portion of the scraper, and races pivotally connecting thescraper to the frame and upon which the scraper may be wholly orpartially inverted for .dumping when the latch mechanism is released.

2. In a scraper and grader, the combination of a wheeled frame, a shovelscraper disposed in the frame and having side extensions at its rear endresting on the frame side, a latch mechanism movable to engage,

and disengage said shovel extensions, a lever mounted on the frame andhaving a 'pivotal connection with the said shovel scraper adjacent itsforward end, braces pivotally connecting the scraper to the frame andhandles carriedby the scraper.

3. In a scraper and grader/the combination of a wheeled frame, a shovelscraper disposed in the frame and having side extensions at its rear endresting on the frame sides, vertical latch members pivoted in the frame,a lever mounted on the frame and having connection with said latchmembers whereby to cause the same to engage and disengage said shovelextensions, means for raising and lowering the forward portion of thescraper, and braces pivotally connecting the scraper to the frame.

4. In a scraper and grader, the combination of a wheeled frameembodying. slotted side members, a shovel scraper mounted in the frame,latching means movable to engage and disengage the rear portion of thescraper, braces pivotally connecting the scraper to the frame, and alever having connect-ions working in the said frame side slots andpivotally connected with the forward portion.v of the scraper whereby toraiseand lower the same.

5. In a scraper and grader, the combination of a wheeled frame havingslotted sides, studs working inthe said side slots, a shovel scraperdisposed in the frame lever arms pivotally connected at one endto theforward portion of the said scraper and rigidly connected at their 0osite ends to the said studs, braces pivotally connecting the scraperwith the frame, latching means mounted on the frame and movable toengage and disengage the rear ortion of the scraper, and a U-shapedlever aving its extremities rigidly connected to the said studs.

6. In a scraper and grader, the combination of a wheeled frame, a shovelscraper disposed in the frame, braces pivotally connected at their rearends to the rear side portions of the scraper and at their forward endsto the frame sides, other braces pivotally connected at their forwardends to the forward portion of the scraper and at their rear ends to theframe and crossing the first named braces, latching means movable to enage the rear portion of the scraper, an means having pivotal connectionwith the forward portion of the scraper for raising and lowering thesame.
